do wool carpets change colour over time? (not fade)

[linspins]

Hello! I'm looking for advice on whether wool carpets initially change colour after they are fitted...The story: I ordered carpet for all 3 of our bedrooms and the landing/stairs, and the local shop said it would be ok to have it fitted as and when we needed it, as we were decorating each room in turn. My understanding from what they told me was that the whole amount of carpet would be ordered at the same time, and that the stock would be kept at the shop. So the first bedroom was fitted last october, and the second one today....and they look slightly different colours! ARGH!! I put an off-cut from one in the other room to check it wasn't just a trick of the light, and it is a little yellower. I called the shop and the owner said that "carpets do change colour slightly over time, due to oxidisation processes that occur in natural materials" and to give it a month and then if we were still unhappy to get back to him. Is this true? Or is he banking on the fact that once all the furniture is back in we won't want the upheaval of changing it all. It doesn't matter too much now, but might really show when the landing carpet is fitted, as one of the joins won't match! Help!
(sorry for long post). xx

I wouldn't have thought that carpets will change colour that quickly.However to expect the retailer to absorb the cost of the carpet for 2-3 months is not really fair.I guess that carpets do vary slightly, like paint and wallpaper batches.

Thanks Teta. We did pay a big deposit for the whole lot, so the retailer wouldn't have lost out financially, and it was the retailers suggestion that we have it fitted in each room when we're ready. I knew from the start that carpet batches, as you say, like paint or wallpaper, vary slightly, so this was exactly the situation I was trying to avoid, but ordering it all at once from the same roll.

Have you asked directly if they are from the same batch?

I'm not sure! When I called after it had been fitted, I was a bit flustered (and baby trying to climb on me), and I think I said something along the lines of " I'm worried that they look a little different because surely they are from the same roll..wasn't it all ordered at once?" and he said "i'd have to look in to it" and the conversation moved on - but it was one of those conversations where both parties are talking a bit on top of each other, and I was trying not to sound negative or cross (in that way that people are always to embarrassed to complain!).

In which case Linspin i would ask him to come and have a look .I know what its like when you have screaming dc's and you are not always taken seriously.Just be polite but firm or even better get your other half to do it.

Yeah, I might delegate. I'm so useless at complaining, I end up apologising to them. I really haven't ever heard of carpets changing colour so swiftly, and the other one was only fitted in autumn, so it's not as if it's faded in the sun, or got ingrained with dirt. I'm all upset as I was so excited to get this room (our bedroom) finally decorated and done. Bother!!

I'm sorry you're upset.
